Yes, using tap water for everything. Not tested, but never a problem I've
noticed.

Perhaps that is what happened (see below)

Right, I do keep them separate and mix just before coating.
My best guess is that "ryberg" was correct with his guess in a private
e-mail. I think I made a "stupid" mistake (my term, not ryberg's). I suspect
that I carefully measured out my "A" solution, then put the "A" down and
instead of picking up the "B" and adding it in, picked up the "A" again and
measured it thinking it was "B". This does account for the printout image
being too yellow and then washing right off the paper.
A shame, I had coated six full sheets of good paper for 16x20 prints. They
were to be part of an order I have to ship on Wednesday. I couldn't print
over the weekend, because of out of town house guests. So, I should now get
my butt in the darkroom and do these over again!
Thanks everyone for the help.
